(Cl. 14S-85) 4 Claims.

`This invention appertains to new and useful improvements in harvestingmachines and more particularly to a beet harvesting machine of thecombined type.

The principal object of the present invention is to provide a combinedbeet harvesting machine which is constructed and operated to pull thebeets, top the same and load the beets into piles.

Another important object of the invention is to provide a combined beetharvesting machine which not only pulls the beets and harvests the same,but also levels the soil after the pulling `operation and places thebeet tops in piles or bunches,

Another object of the invention is to provide a machine of the characterstated which is of simple construction yet durable in operation and notsusceptible to the ready development of defects.

These and various other important objects and advantages of theinvention will become apparent to the reader ofthe followingspecification:

In the drawings- Figure 1 represents a side elevational view of theapparatus.

Figure 2 is a top plan view.

Figure 3 is a longitudinal sectional View.

Figure 4 is a cross sectional view on a line 4-4 of Figure 3 and showinga loading truck adjacent to the machine.

Figure 5 is a sectional view on the line 5-5 of Figure 3.

Figure 6 is a sectional view through one of the cutting assemblies.

Figure 7 is a cross sectional View through the topped beet conveyor.

Figure 8 is a cross sectional view taken substantially on a line 8-8 ofFigure 1.

Figure 9 is a fragmentary detailed sectional view of the drive for thelateral conveyor.

Referring to the drawings, wherein like numerals designate like parts,it can be seen in the drawings that numeral 5 represents the platformsupported by the frame 6.

A narrow frame 1 inclines forwardly from the frame 5 for supporting thebeet puller blades 8. Arms 9 extend downwardly to support the pullerblades 8 and these arms also support the forward shaft I on which arethe sprockets II and trained over these sprockets II and the sprocketsI2 on the shaft I3 are the chains I4 bridged by bars I carrying thespikes I6 which serve to feed the pulled beets backwardly onto theinclinedforward end lportion of the conveyor belt Numeral I3 denotes themain drive shaft which at its forward end portion has the bevel gear I9meshing with the bevel gear 20 on the shaft 2l overlying the inclinedportion I1 of the belt and a chain drive 22 is taken from this shaft 2|to the shaft I3 for driving the said beet picking mechanism aforedescribed. l

Numeral 23 denotes a yoke whichy straddlesthe frame 1 and has the drafteye 24 at `its forwardmost portion. l The endless belt I1 extendslongitudinally o the machine and is first disposed over the rollers25-26 supported by the posts 21. The belt then extends rearwardly andpasses over the rear roller 28 which is on the shaft 29 drivenrby thebelt 30 which is trained over the pulley 3l on the shaft 32 with the twoknives 33. The shaft 32 is trained through the post 34 and each diskblade has the disk bars 35 disposed thereover.

A guard rail 36 extends along the outside `of each blade so as toprotect the workman standing on the platform 5 adjacent the belt I1.

A second pair of cutting disks 31 are provided forward of the blades 33and each of these has the guard 38. These blades 31 are carried by theshaft 39 on which is a pulley 40.and trained over this pulley 40 and thepulley 4I on the shaft 32 is the belt 42 whereby the shaft 39 and itsblades 31 are driven by the shaft 32. The blades 31 are likewiseprovided with guard rails 43,

The rear terminus of the belt I1 is overlying the hopper 44 which has aslanting bottom 45 and a gate 46 which is opened by the control rod 41which extends to some manual control, preferably foot pedals.

Underlying the belt I1 is the cross-shaped structure 48 in which theendless conveyor 49 operates. The upper portions of the side walls ofthis trough slant outwardly as at a-a for the purpose of catching toppedbeets which are dropped onto the conveyor by the Workmen.

A `laterally extending conveyor 50 operating between the side walls `5Ihas its lower end terminating in the box 5Ia, and rising from this box5Ia which has a slanting bottom 52 is an elevator made up of theinclined side Walls 53 and the endless belt 54 operating therein.

This endless belt 54 which is provided with transversely extendingcleats 55 is disposed over the upper and lower rolls on the shaft 56 and51 and the chain 58 taken off of the shaft 29 serves to drive thiselevator which has a laterally inclined chute 59 extending from itsupper end to terminate over the beet bin 60 which is supported by theupright 6I' on the platform 5 and overlying the forward portion of theconveyor I1.

K bar is dragged Thlsbin is' provided with the sloping bottom 62 and hasthe gate 63 at its lower end which will. open when manually controlledor When a denite weight of beets loaded in the bin forces against thesame. Extending outwardly beyond the gate 63 is the chute 64 fordelivering the discharged beets into a truck 65 or to form piles on theground.

The frame 6 -is supported by the Wheels 66 while the forward portion ofthe frame l` is supported by the wheels E1 and a drag bar 68 tends tolevel the soil after the beets have been pulled, and this the frame 6.

by the chains 69 extending from 50 has one shaft 61 driven` bythe bevelgears 5 8 l and 69 and the chain 10 taken off of the avfore- Almentioned conveyor shaft 29.v 4

While the foregoing specification setsforth the invention in speciiicterms, it is to be understood that numerous .changes in the shape, sileand materialsmay be .resorted to Without departingfroinf'theAspirit-'and scope of the invention as claimed hereinafter, v
